Overview
ISO 10303-108:2005/Cor 2:2014 is a technical corrigendum to the international standard for industrial automation systems and integration, specifically focusing on Product data representation and exchange. Part 108 covers the Integrated application resource for parameterization and constraints in explicit geometric product models. This corrigendum, published by the International Organization for Standardization (ISO), addresses corrections and clarifications in the standard’s EXPRESS code, making vital improvements that ensure precise data modeling and exchange in product development and industrial automation.
Key Topics
- Parameterization & Constraints: Provides standardized methods for defining parameters and constraints in explicit geometric product models, essential for consistent product data representation.
- EXPRESS Code Corrections: Amends WHERE rules, attribute qualifications, and function coding in the EXPRESS data modeling language, improving logical precision and interoperability.
- Entity & Function Updates: Revises definitions and code for entities like simultaneous_constraint_group and neutral_sketch_representation, as well as functions such as check_curve_planarity and get_plane_of_implicit_geometry, to refine product model representations.
- Schema Identification: Updates object identifiers for schema components, ensuring unambiguous referencing of parameterization, constraint, and sketch schemas within open information systems.
- Compliance & Clarity: Ensures that all reference statements and schema attributions follow naming conventions and alignment, aiding implementation for automation and integration contexts.
Applications
- Industrial CAD Systems: Enables robust parameter and constraint management for explicit product geometry, streamlining the creation, editing, and exchange of detailed CAD data.
- Automation Workflows: Facilitates integration across automation systems by standardizing data structures, supporting reliable communication between design, planning, and manufacturing tools.
- Product Lifecycle Management (PLM): Enhances data exchange in PLM systems, supporting consistent model updates and constraint validations through precise standard definitions.
- Interoperable Data Exchange: Promotes compatibility across various engineering and manufacturing applications by refining EXPRESS schema and ensuring correct interpretation of geometric and constraint data.
- Quality Assurance: Prevents misinterpretation due to ambiguous schema references or outdated code, thereby reducing errors in automated processing and product data management.
Related Standards
- ISO 10303 Series (STEP): The broader family of standards for the exchange and representation of product data in industrial automation systems.
- ISO/IEC 8824-1: Defines the semantics of object identifiers used within the standard for clear schema referencing.
- ISO 10303-108:2005 and Cor.1: The original standard and first corrigendum provide foundational and earlier corrective content.
- ISO 13584: Specifies reference data libraries and generic expressions schemas, relevant for EXPRESS code referencing and integration.
By providing essential corrections and clarifications to Part 108 of ISO 10303, this technical corrigendum strengthens the reliability of geometric product model parameterization and constraint management. Adhering to ISO 10303-108:2005/Cor 2:2014 assures stakeholders that their product data exchange processes meet the latest international requirements for accuracy, interoperability, and automation system integration. This is critical for industries utilizing CAD, PLM, and digital manufacturing workflows, where precise data exchange underpins efficiency, quality, and competitiveness.
